The experiment results indicted that there existed fairly good linearity between the grain sizes and longitudinal wave velocities when the measurements were done with 5p14z probe.
实验结果表明，用5 P 14Z探头测得的纵波声速与晶粒尺寸之间有很好的线性关系。
Through the case study we analyze the definitions, measurements and sizes of the equivalent aperture in different specifications home and abroad.
通过案例比较分析了国内外不同规范中对等效孔径的定义、测定方法、大小关系等。
